==Biography== Zeitouni received his bachelor's degree in electrical engineering in 1980 from the Technion.

He obtained in 1986 his doctorate in electrical engineering under the supervision of Moshe Zakai with the thesis ''Bounds on the Conditional Density and Maximum a posteriori Estimators for the Nonlinear Filtering Problem''.<ref>{{MathGenealogy|id=81627}}</ref> As a postdoc he was a visiting assistant professor at Brown University and at the Laboratory for Information and Decision Systems at MIT. He joined the Technion in 1989 as senior lecturer, and was promoted in 1991 to associate professor, and in 1997 to full professor in the department of electrical engineering. He is now a professor of Mathematics at the Weizmann Institute and at the Courant Institute, and was from 2002 to 2013 a part-time professor at the University of Minnesota.<ref>{{cite web|title=Zetouni Moves to Weizmann Institute of Science|website=School of Mathematics, University of Minnesota|date=29 May 2013|url=https://math.umn.edu/news/zeitouni-moves-weizmann-institute-science}}</ref>

His research deals with stochastic processes and filtering theory with applications to control theory (electrical engineering), the spectral theory of random matrices, the theory of large deviations in probability theory, motion in random media, and extremes of logarithmically correlated fields.

He was Invited Speaker with the talk ''Random Walks in Random Environments'' at the ICM in Beijing in 2002. Zeitouni is a Fellow of the American Mathematical Society, member of the American Academy of Arts and Sciences, the National Academy of Sciences, and the Israel Academy of Sciences and Humanities.

He is married and has two children.
